As the resistance of a circuit increases, the current will
Natalija [7]

As the resistance of a circuit increases, the current will decreases.

<h3>What is ohm’s law?</h3>

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

When all physical parameters and temperature are constant,

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

This current-voltage connection may be expressed mathematically by Ohm's law as;

V=IR

If the voltage is constant, the resistance of the circuit will be inversely proportional to the current.

Hence,as the resistance of a circuit increases, the current will decreases.

Problem: The circular blad on a radial arm saw is turning at262
kobusy [5.1K]

Answer:

Net torque, \tau=-0.033\ N-m

Explanation:

It is given that,

Initial angular speed of the blade, \omega_i=262\ rad/s

Final angular speed of the blade, \omega_f=85\ rad/s

Time, t = 18 s

Radius of the disk, r = 0.13 m

Mass of the disk, m = 0.4 kg

We need to find the net torque applied to the blade. We know that in rotational mechanics the net torque acting on an object is equal to the product of moment of inertia and the angular acceleration such that,

\tau=I\times \alpha

The moment of inertia of the disk, I=\dfrac{mr^2}{2}

\tau=\dfrac{mr^2}{2}\times \dfrac{\omega_f-\omega_i}{t}

\tau=\dfrac{0.4\times (0.13)^2}{2}\times \dfrac{85-262}{18}

\tau=-0.033\ N-m

Negative sign shows that the net torque is acting in the opposite direction of its motion. Hence, this is the required solution.

Planets use carbon dioxide for?
creativ13 [48]
In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food; food that we use, too, when we eat plants or animals that have eaten plants and they release the oxygen into the atmosphere.
So it’s PHOTOSYNTHESIS

Why doesn't a radio operating with two batteries function when one of the batteries is reversed? ​
bulgar [2K]

Answer:

If you have two batteries and they have precisely the same voltage then placing one backwards will effectively cancel out the voltages and no current will flow. However, batteries aren't like that. The slightest difference in voltages mean that current will flow.
